Description

Drug compound for the control of blood glucose, blood lipids and weight

Technology Field

This invention belongs to the medicine and health food field. Specifically, this invention involves drug compound and health food compound, consisting of water-insoluble alcohol-soluble extract of Radix Glycyrrhizae and Lycium chinense, used to control blood sugar, blood lipids and body weight, etc. Furthermore, there is no side effect with the long-term use.

Technology Background

Wolfberry, also known as fruit of the Chinese wolfberry or Goji Berry, produced in Tianjin, Henan, Hebei, Shanxi, Ningxia, etc., is the fruit of solanaceae Lycium deciduous shrub. Wolfberry contains 14 kinds of amino acids, as well as betaine, zeaxanthine, physalin and other components, with such effect as delaying senescence.

However, the property of wolfberry is sweet and warm, and its warm efficacy is especially strong, so it is not suitable for people with unrecovered internal heat, high blood pressure, colds, fever, body inflammation or diarrhea. Healthy people taking higher dose for long term are also prone to heat disease, reflected in the clinical symptom of easy sweating and hair loss in serious condition.

Radix Glycyrrhizae's property is sweet, and the raw Radix Glycyrrhizae's property is mild. It can rcpair the insufficiency of licnogastric, rcmovc thc heart-fire, and have the efficacies of anti-tussive, anti-inflammation and tonif'ing Qi. However, Radix Glycyrrhizae contains licorice acids compound, and has an effect similar to glucocorticoid. Long-term use will cause imbalance of sodium and potassium ions in the cell, and thus resulting in elevated blood sugar and blood pressure, so people with hypertension, hyperglycemia, obesity, kidney and heart disease and irregular menstruation shafl use it with caution.

Therefore, in respect of the traditional Chinese medicine, there is no program with the collocation ofonlywolfberry and Radix Glycyrrhizae to treat disease or for health care, especially the guide for long-term use in large doses. For example, the Chinese Patent No. 00112777 describes wolfberry, licorice, ginseng and other dozens of crude drug are made into medicines in collocation, used for the prevention and treatment of hyperlipidemia, hyperglycemia and other diseases. The medicine reduces the actual amount of Chinese wolfbcrry and licorice, but the formula is complicated, and a lot of raw materials and product quality is difficult to control, so it is not easy to get a stabilizing and exact efficacy. Chinese Patent No. 00135732 describes more than kinds of ingredients such as wolfbcrry, licorice and lotus leaves are made into health-care liquid, and then mixed into grape wine to become medicated wine with the efficacies of regulating blood lipids, blood pressure, and blood sugar as well as the efficacy of reducing weight. However, this medicine is not only difficult to control the quality of many raw materials and products, and not easy to get a stabilizing and exact effect, which is similar with the previous one, but also has a more narrow scope of applicable crowd due to its medicated wine form.

Other relevant current technologies published also have the above-mentioned drawbacks. For example, the health-care liquid recorded in Chinese Patent No. 02125698 not only has too many raw materials, but also needs microbial fermentation preparation, which increases the difficulty in the control of product quality stability; the major ingredient of the health foods recorded in Chinese Patent No. 02155649 is garlic, while the contents ofwolfbcrry and Radix Glycyrrhizac are very low, and garlic products is not suitable for long-term large doses; the major ingredients of the health tea recorded in China Patent 200610121779 are not wolfberry and Radix Glycyrrhizae but gynostemma pentaphylla and Linearstripc Rabdosia Herb.

Hyperglycemia, hyperlipidemia and obesity are "rich man's disease" caused by the modern living habits. There is no permanent control method for these diseases, and the patients need long-term medication for controllability treatment. Therefore, wolfberry can't become long-term high-dose medication for these diseases due to the limitation of its side effect (where safety is a primary consideration). And there is also no health product with accurate curative effect that can be used for long-term large doses.

After the long and arduous research and with some luck, the inventor surprisingly found out that the water-insoluble alcohol-soluble extract of Radix Glycyrrhizae can be in collocation with wolfberry to achieve a collaborative effect and significantly improve the control effectiveness of blood glucose, blood lipids and body weight. More unexpected is that the compound can be taken in long-term large doses without side effects. Furthermore, the preparation process of collocation of wolfberry and Radix Glycyrrhizae is relatively simple, easy to control the product quality. The water-insoluble alcohol-soluble extract of Radix Glycyrrhizae is conducive to the crumbling of woltberry, which facilitates the preparation process.

The prepared products have a longer preservation duration and shelf-life.

This invention quoted the publicly available literatures so as to describe this invention more clearly, and their fitll-tcxt contents are incorporated herein as if their fill text has been repeated in this paper.

For easy understanding, the following part will describe this invention with specific embodiments. It must be specially pointed out that these descriptions are demonstrative only and do not constitute a restriction on the scope of this invention.

Other technical plans of this invention can be obtained by the method described in embodiments. According to the description of this instnzction, many changes of this invention are obvious for technicians of its field.

Specific Implementation methods Plant raw materials and chemical reagents used in specific embodiments are all conventional materials bought fixm the market.

Embodiment! Preparation of experimental medIcines (1) Preparation of licorice extract 0018 Soak lOOg of comminutcd Ural licorice herb (can be purchased thm Beijing TRT, Beijing, China) into 800m1 water of 65 °C; seven hours later, filter the solution, throw away the liquid and retain the solid; wash the solid with water of 60t for three times respectively, and each time use 800ml water to soak the solid for 10mm and that filter the solution and throw away the liquid. Put the washed licorice into a 60t drying oven for 17 hours. Add 250nil 95% (VIV) ethanol into the solid after drying, put the container into 85 t water for circumfluence bath for 1.5 hours, then filter the solution and retain the liquid; add 250m1 95% (VAT) ethanol into the filtered residue, put the container into 85t water for circumfluence bath for 1.5 hours, then filter the solution and retain the liquid; mix the two parts of filtered liquid, dry it under 60t for 20 hours, 3.9g licorice extract will be obtained, named (3018.

(2) Preparation of CK-woliberry powder (contrast) Take 20g wolfbeny (can be purchased from Beijing TRT, Beijin& China), thy under 60t until the water content is anng 12 -13% (w/w), comminute them by FW135 type comminutor (purchased fitm Tianjin Taisite Instrument Co., LTD), the comminutot's rotational speed is 24000r/min and the comminution time is 30s.

Woliberry powder can not pass through a 100 mesh sieve, if it is a 80 mesh sieve, we find that about 80% of wolfbeny powder can not pass through the sieve, this might because that the content of polysaceharide in wolfberry is relatively high, then it is not easy to comminute, thus the production is affected. Therefore, use a 60 mesh sieve, about 90% of wolfbeny powder can pass through, and the particle diameter of CK-wolfberry powder obtained by this way is no more than 60 meshes.

Conduct the stability test at the room temperature of 22 to 28 t, and the relative humidity of 75%, it's found that CK-woliberry powder will be caked within 12 hours, indicating that CK-wollbcny powder is hard to store and guarantee its quality (3) Preparation of 0.5-G018 woilbeny powder Refer to the method in (2) mentioned above, take 20g wolfberry, dry them and mix them with 0.lg (3018, then comminute them by FWI3S type comminutor, the comminutofs rotational speed is 24000r/min and the comminution time is 30s. use a mesh sieve, we find that about 50% of the mixed powder can not pass through, although it is can be seen that adding G018 is conducive to the comminution of woitherry, thc trappcd amount of mixed powder still can not be ignored, so we use a mesh sieve, then more than 95% of woitherry powder can pass through, and the particle diameter of wolfberry powder obtained by this way is not more than 60 mesh.

Conduct the stability test at the room temperature of 22 to 28 C, and the relative humidity of 75%, it's found out that 0.5-G018 woltheny powder will not be caked within 24 hours, so it is much easier to store and guarantee quality compared to CK-wolfbeny powder.

(4) Preparation of2-G018 wolfberry powder Refer to the method in (2) mentioned above, take 20g wolfbeny, dry them and mix them with 0.4g GO 18, then comminute them by FWI3S type comminutor with the rotational speed of 24,000r/min and comminution time of 30s. Filter the mixed powder by a 80-mesh sieve (only less than 5% of the mixed powder can not pass through), and the particle diameter of2-G018 wolfberry powder obtained by this way is no more than 80 meshes.

Conduct the stability test at the room temperature of 22 to 28 C, and the relative humidity of 75%, it's found out that 2-GO 18 wolfberry powder will not be caked within 72 hours, so it has the advantage of being much easier to store and guarantee quality compared to CK-woltherry powder, and under the condition of sealed package, its quality guarantee period is expected to be 6 months longer than that of CK-wolfberry powder with the same package.

(5) Preparation of formulations The above CK-woltherry powder, O.5-G018 woltbeny powder and 2-G018 woitherry powder can be directly put into capsules to make capsule formulation rcspcctiv&y, and they can also be made into water pill tbrmulation by water pill machine, and they can also be made into the shape of cake.

Embodiment 2 Clinical observation on the short-term efficacy of all drugs in Embodiment 1 on postprandial blood glucose controlling for high-blood-glucose patient The postprandial blood glucose of Type 2 diabetics insensitive to insulin is an important index of abnormal glucose metabolism, so the effect of drugs in reducing blood glucose can be inspected through the examination on postprandial blood glucose of diabetics in this embodiment. Implement according to the clinical experiment standard issued by the State Food and Drug Administration, people after random grouping (45-56 years old, three in one group, fasting blood glucose is above 7.5mM/L and postprandial blood glucose is above lOmM/L) take orally CK-wolfberry powder, O.5-G018 wolfberry powder, 2-G018 wolfberry powder and ordinary food (soybean) respectively prepared in Embodiment 1, and the dose they intake is metered by the above powder or soybean, all are 20g. 30mm after taking the medicine before the meal in the morning, test the blood glucose two hours after patients eat 300g boiled corn and the results are shown in Table I. The results show that CK-wolfberry powder, 0.5-GO 18 woltberry powder and 2-GO 18 wolfberry powder all play a significant role in the control of postprandial blood glucose of diabetics with high blood sugar, and its efficacy works immediately, which is obviously better than the efficacy of ordinary food (soybean), among them the effect of 0.5-GO 18 wolfbeny powder and 2-GOl 8 wolfbeny powder is better than that of CK-wolfberry powder alone.

Four weeks later, draw blood and assay the blood glucose, blood fat and body weight, and the results are shown in the following Table II.

The results show that although ordinary food (soybean) plays little role in lowering cholesterol, it has no effect of blood glucose reduction or losing weight; using ClC-wolfberry powder alone results in the blood glucose reduction of less than 10%, blood fat reduction of less than 3% and weight reduction of 2Kg, which is completely worse than using 2-G018 wolfberry powder; 243018 wolfberry powder achieves an average blood glucose reduction of about 29.1%, average serum cholesterol reduction of about 46.6% and average weight reduction of 5.3Kg. In addition to the difference in efficacy, it is even more remarkable that three months later after taking 20g of CK-wolfberry powder every day, the patient become prone to sweating, and even one patient suffers the side effect of hair loss; in contrast, take 20g of 2-6018 w&fberry powder every day, one week later, the patients' appetite decreases but their physical strength increases, which is beneficial for patients with high cholesterol and high blood sugar and is not a side effect, without such side effect as easy sweating and hair loss.
